Frightening dashcam footage shows London Cab T-boned at Perth intersection

The footage was captured by the dashcam of a car waiting next to the cab at the Wellington/Lord street lights.

It shows the light turn green and the cab moving forward before another car hurtles from the right, crashing into the cab at what appears to be a full normal road speed.

"I am just lucky enough otherwise my wife and I would be a disaster as I was driving a Toyota HiAce van," the camera owner wrote to Dashcam Owners Australia, who posted his footage online.

Commenters pointed out the light was red for about 10 seconds before the dark car came through.

"Their head had to be in their phone to have missed it," one Facebook user speculated.

But the tow truck driver who cleared the dark-coloured sedan told WAtoday the driver had another story.

"The driver said it was a yellow light," he said.

"The car was probably a write-off."

Police attended to manage traffic around the incident and would investigate any further report that arose from the incident, a spokeswoman said.

Black & White Cabs confirmed their driver was shaken but unharmed. 

Perth Fire and Rescue Service attended to secure the scene but did not need to free anyone from their vehicle. St John Ambulance was notified but no one was hurt.
